Bone repair system and method

A system for the percutaneous repair of a first and second bone segments of a fractured bone in a patient, comprising:

• at least a first and second tether each having a proximal end and a distal end;
• a reinforcing member having a hole at one end and at least one elongated slot at another end, wherein the distal end of the first tether is arranged to be passed through the hole and the distal end of the second tether is arranged to be passed through the slot;
• at least a first and second outer fastener each having a longitudinal channel for passing the proximal ends of the first and second tethers therethrough, respectively;
• and
• at least a first and second inner fastener arranged to be secured on the distal ends of the first and second tether, respectively, to retain the reinforcing member on the first and second tethers, wherein the first and second tether distal ends are threaded for receiving the first and second inner fasteners thereon, respectively;
• wherein the first and second tethers are arranged to be received through holes in the first and second bone segments, respectively, for pulling the reinforcing member into engagement with the first and second bone segments, wherein the first outer and inner fasteners are secured through the reinforcing member hole and the second outer and inner fasteners are secured through the reinforcing member slot to secure the reinforcing member to the first and second bone segments.

A kit for surgical repair of a fractured bone involving a first bone segment and a second bone segment, the first and second bone segments each having an internal surface and an opposed external surface, the kit comprising:

• a drill guide for facilitating drilling of a first hole in the first bone segment and a second hole in the second bone segment;
• at least a first and second tether each having a proximal end and a distal end;
• at least one reinforcing member having a first opening at one end arranged to receive the first tether and at least one second opening at another end arranged to receive the second tether;
• at least a first and second outer fastener configured to be disposed at the external surface of the first and second bone segments, each outer fastener having a longitudinal channel for passing the first and second tethers therethrough, respectively;
• and
• at least a first and second inner fastener configured to be disposed at the internal surface of the first and second bone segments and each arranged to be received on the distal ends of the first and second tethers, respectively, to retain the reinforcing member on the first and second tethers and engage the reinforcing member against the internal surface of the first and second bone segments;
• wherein the first and second tethers are arranged to be passed through the first and second holes, respectively, for pulling the reinforcing member into engagement with the first and second bone segments, wherein the first outer and inner fasteners are configured to concurrently abut the external and internal surfaces, respectively, and be secured to each other through the reinforcing member first opening, and the second outer and inner fasteners are configured to concurrently abut the external and internal surfaces, respectively, and be secured to each other through the reinforcing member second opening to secure the reinforcing member to the first and second bone segments.

A kit for surgical repair of a fractured bone involving a first bone segment and a second bone segment, comprising:

• a hollow trocar for engaging the first and second bone segments;
• a drill guide arranged to be received through the trocar for facilitating drilling of a first hole in the first bone segment and a second hole in the second bone segment;
• at least a first and second tether each having a proximal end and a distal end;
• at least one reinforcing member having a hole at one end arranged to receive the first tether and at least one elongated slot at another end arranged to receive the second tether;
• at least a first and second outer fastener each having a longitudinal channel for passing the first and second tethers therethrough, respectively;
• and
• at least a first and second inner fastener each arranged to be received on the distal ends of the first and second tethers, respectively, wherein the first and second tether distal ends are threaded for receiving the first and second inner fasteners thereon, respectively;
• wherein the first and second tethers are arranged to be passed through the first and second holes, respectively, for pulling the reinforcing member into engagement with the first and second bone segments, wherein the first outer and inner fasteners secured through the reinforcing member hole and the second outer and inner fasteners secured through the reinforcing member slot to secure the reinforcing member to the first and second bone segments.
